To prevent the development of settlements and heave-up of facilities, the compensation grouting technique is used. The article reports the data of numerical simulation of the compensation grouting process as illustrated by the physical experiment performed by Luca Mazini, Ph.D. from La Sapienza Rome University (Rome, Italy). Simulation is performed with the JulyS program developed by the article authors for the ECM. The program implements the finite element method in a three-dimensional approach with Professor L.N.Rasskazov’s non-linear “energy” soil model. Different simulation of supplementary volume arrangement in the sandy soil under grouting in the finite element method approach is reviewed. The numerical simulation data are compared with the field experiment.

Abstract The paper describes the intention of the authors to determine whether it is possible to predict relative belt edge endurance for radial passenger car tires using the finite element method. Three groups of tires with different belt edge configurations were tested on a fleet test in an attempt to validate predictions from the finite element results. A two-dimensional, axisymmetric finite element analysis was first used to determine if the results from such an analysis, with emphasis on the shear deformations between the belts, could be used to predict a relative ranking for belt edge endurance. It is shown that such an analysis can lead to erroneous conclusions. A three-dimensional analysis in which tires are modeled under free rotation and static vertical loading was performed next. This approach resulted in an improvement in the quality of the correlations. The differences in the predicted values of various stress analysis parameters for the three belt edge configurations are studied and their implication on predicting belt edge endurance is discussed.

This paper is concerned with the convergence of the h-p version of the finite element method for three dimensional Poisson problems with edge singularity on quasi-uniform meshes. First, we present the theoretical results for the convergence of the h-p version of the finite element method with quasi-uniform meshes for elliptic problems on polyhedral domains on smooth functions in the framework of Jacobi-weighted Sobolev spaces. Second, we investigate and analyze numerical results for three dimensional Poission problems with edge singularity. Finally, we verified the theoretical predictions by the numerical computation.
